A rainy Wednesday evening in January. The adjoining room of the Helios-Mariahilf cafeteria fills up with young couples, and many of the women have a bulging stomach. Rush hour traffic on the four-lane B 73 rushes beneath the huge window front, and the lettering of a fast-food chain glows on the opposite side of the street. There are more idyllic places to have a baby. But those who live in Hamburg south of the Elbe have little choice, the Mariahilf Clinic in the district Harburg is the only maternity clinic in the south of Hamburg. There are ten north of the Elbe.
